Found bolt laying in transmission oil pan

[Kbcattle13]

So I dropped the oil pan on my 48re transmission attempting to diagnose why the transmission quit going forward or back and found a short hollow bolt laying on top of the valve body. The bolt is only about 1/2" long of threads maybe and is hollowed out. Has a wide flat head approximately 3/4" hex head. Any ideas where this cake from? Haven't dropped the valve body yet but planning to tomorrow. Oil smells burnt as well

I found something like that in a GM transmission once but that one still worked.

That looks like some kind of drain plug bolt to me.

@crunch that's what I thought but can't figure out for the life of me where it would've came from inside the transmission

I found a VERY detailed manual on the 48RE here:

I looked at every page and did not see a plug that looks like that one anywhere. I would guess it either plugs a galley or holds a spring and ball/valve in a galley. Where it goes, I don't know.

yeah I've come across that site already and studied all 181 pages and also found nothing. thinking maybe my torque converter went but that still doesnt explain the bolt/ plug

That makes a lot of sense to me, but I don't know much about the innards of modern transmissions. If that's what it is, Kbcattle13 should be worried because he would still have a little steel ball and a spring to find in there.
